It is scientifically proven that men are “the weaker sex”! Duke University researchers have published a study that shows that over the past 250 years, women have been more resilient than men, especially to epidemics and hunger. Man is threatened with extinction because his signature, his Y-chromosome, is in ruins and has been losing its genes for millennia.
Recently however the speed of the degradation has increased because many men are wearing too-tight pants and are also exposed to rising temperatures, pollution, and electromagnetic waves.
There’s been an alarming 40% drop in the average male sperm count in the last 20 years, compounded by a drop in quality. Some researchers think it’s just an important problem as global warming.
We live surrounded by chemicals. The toxicity of phthalates on germ cells, precursors of sperm, is no longer in doubt. So is the toxicity of pesticides, which also contribute to sperm alteration.
Foods are suspected of being a direct cause in the degradation of sperm and alcohol and tobacco are probably the main causes. Smoking destroys the blood vessels of the male reproductive system. In the penis, this is responsible for changing the quality and duration of an erection. In the testicles, vascular changes will lead to more or less irreversible destruction of sperm production.
The testicles must be cooled
The heat was also mentioned because sperm production is extremely sensitive to temperature. Sperm must be stored at temperatures between 91,4 to 93,2°F. Depending on the temperature, the bursa is contracted or relaxed to maintain a constant temperature. This is why they are outside the body!
An increase in testicular temperature will slow down or even stop spermatogenesis. Based on this observation, many researchers are suspecting that the main cause for this could the wearing too-tight pants/jeans.
Some blame it on the stress to which our modern world is accustomed, but here too we must show that our modern life is more stressful than the life of those that experienced war and hunger.
